centripetal force in atom?

Question

there is gravititional and centripetal force in atom.....i think it is planet in solar system.is that true?

Answer 1

"Centripetal" means center-pointing. If an object undergoes uniform circular motion then there is some unbalanced force that is centripetal. For planets, that force is a gravitational one. For electrons in atoms that force is an electrical force (though it is not correct to think of electrons in circular motion because of the quantum nature of matter at such small sizes.)

Answer 2

The orbits of an electron about its nucleus and a planet around its sun have similarities and differences. Both are roughly circular. In both cases, an attractive force between a massive central body and a light orbiting body accelerates the light body just enough to maintain its orbit. For the planet, it's gravitational and large scale. For the electron, it's electrostatic and small scale. Small enough that quantum effects need to be considered. The length of the electon orbit needs to be an integral multiple of the wavelength of its wavefunction. The peak of the wavefunction needs to be at the same point for each trip around the orbit.

The planet can slow down by an infinitesimal amount and then assume an infinitesimally smaller orbit. Not so the electron. The electron must slow down enough so that its new orbit is still an integral number of wavelengths, but just a smaller integer. To maintain conservation of energy, it must emit a photon whose energy is exactly the difference of electron energies in the two orbits.

If this doesn't answer your question, ask it clearly.

Answer 3

Atoms are "held together" by electric charge and the strong nuclear force, neither of which have a thing to do with planets in a solar system.

Answer 4

there is no such element as centrifugal rigidity. it is what's called a 'fictitious rigidity' occuring in rotating frames of reference. The centripetal rigidity that holding planets in orbit around the sunlight is in basic terms gravity. The centripetal rigidity holding electrons in orbit round atomic nuclei is electrostatic charm. (notwithstanding in quantum mechanics, some atomic electron states do no longer somewhat correspond to rotation.) The time period 'vacuum' in basic terms ability the absence of count number, no longer the absence of fields. notwithstanding, a so-called vacuum is somewhat a complicated seething sea of digital debris called 'the quantum foam'. The debris come out and in of life in truly couple of minutes scales. E.g. see link.

Answer 5

This is the biggest problem currently facing America.

We allow kids to study physics who have not yet learned spelling and grammar.

Answer 6

You already answered your question. Does it matter. As long as it balances out we will be fine.
